The electronic world in the film was accomplished with a unique system of animation and processing that was conceived specifically for the film. This involved creating numerous high-contrast mattes for different elements of a particular shot (or frame), such as the body matte, circuit reveal, face reveal, etc. Each of these mattes were processed one pass at a time by exposing a piece of film, backing it up in the camera, and then exposing the next element - sometimes up to 25 different passes were done on a single piece of film. These were all compiled in-camera, so that there was no need for optical compositing.

This set includes 4 different cels, all measuring approximately 20" x 12.5", and having animation stand registration holes at the bottom.

The cels relating to the character in the shot are:

- Continuous tone image of the actor in costume, marked "CT" for continuous tone

- Circuit reveal, marked “CR” (with ink touch up)

- Inked Kodalith of the High contrast negative image used as a body matte, marked “P"

- Face reveal, 2nd pass, marked “F”

All of these elements were needed to create a single frame of a single shot for the film, representing what an enormous undertaking it was to produce. These elements have been kept together ever since production wrapped and are still in the original cardboard box from the production. While single Tron "continuous tone" Kodaliths have surfaced before, we have never seen a full set of elements and mats offered together like this on the collector's market before.

In addition to the Kodaliths being used in the creation of this shot for the film itself, this image was also selected to be a publicity still for the film. These publicity stills were initially created for the National Association of Theater Owners convention in Las Vegas, in the fall of 1981.

As this set was also used in creating the publicity still, additional material relating to that process are included here:

- Color publicity still with caption and copyright notice

- Black and white publicity still

- Exposure sheet and test wedge dated 10/26/1981, used in testing exposures for elements in the creation of the publicity still

- Exposure sheet and test wedge dated 10/30/1981, used in testing exposures for elements in the creation of the publicity still

All of these items are in relation to the same single frame of “Sark With Disk” and were used in creating publicity stills for the film before its release.

The two included publicity photos, one color 3" x 2.5" and one black and white 5" x 4", come stored in plastic sleeves and include an original typed caption and copyright notice.

The test wedges are short strips of film that are shot during production to test and evaluate various exposures for color and diffusion. From them, the correct exposure of each element would be selected, and the final publicity still would be printed.

Additional information on the technical process of creating the visual effects for the film can be seen in the attached article scan.
